How to setup guest WiFi on Fitz!Box as access point

Networking

Hi, I have the following setup as shown in the picture below.
I have activated the guest WiFi on the Fritzbox. With mobile devices, I can connect mobile devices to the guest WiFi, but the devices can’t get access to the internet. The devices get a completely different IP range (e.g. 192.169.128.123). The Fritzbox is connected via LAN to the IPFire firewall.

How to set up my devices correctly to be able to use the guest WiFi?

And “Familie WiFi” devices are able to connect to internet OK?

If that’s the case then it looks like DHCP not set on Fritzbox for Guests.

Guest access is not available if the FRITZ!Box is using the existing internet connection of another router (IP client mode).

First, determine where the devices obtain addresses from this range.
